future. Our inability to understand and correctly model the underlying 

 processes, combined with the natural variation and the uncertainty in 

 predicting future storms, precludes the development of a model based on first 

 principles. Consequently, we must use simpler models for guidance and 

 combine that guidance with other sources of data, as described above, and 

 experienced engineering judgment. 



123. Similar guidance is a cornerstone of other FEMA procedures. Use 

 of historical data and engineering judgment is an often repeated recommen- 

 dation in the "Guidelines for Identifying Coastal High Hazard Zones" (US Army 

 Engineer District, Galveston 1975). With reference to sand dunes, this 

 report states, 



In many instances, substantial sand dunes with heights of 15 

 ft above sea level and base widths of several hundred feet 

 have been swept away by storm surge and accompanying waves. 

 Unless historical data indicate that sand dunes in the area 

 have repeatedly withstood wave attack during storms, they 

 should not be considered as effective surge and wave barriers.
